REGISTERING AND SQUARING MACHINE.

Application filed April 3, 1919. Serial No. 287,265.

' 7 '0 all whom it may concern Be it known that I, VERNON RoYLn, acitizen of the United States, and resident of Paterson, in thecounty ofPassaic and State of New Jersey, have invented a. new and usefulImprovement in Registering and Squaring Machines, of which the followingis a specification.

This invention relates to registering and squaring machines with theobject in view ofproviding such a device which is sturdy and relativelysimple in construction while adapted for accurate use in a wide field ofoperation.

Another object is to produce such an apparatus in which the work may bemounted in a single holder and manipulated in con-- nection with asquaring and lining device so as to enable the operator to rapidly andaccurately determine the content to be re- ,tained in the work and tosquare the same with respect to the edge of the negative or plate, asthe case may be.

Another object is to provide such a ma- 26 chine which is fitted withmeans for briljliantly illuminating the work (negative) from beneath,and also for intensifying the illumination at any desired portion of thework.

Another object consists in providing such an apparatus which containsimproved. mechanism for accurately adjusting the work holder withrespect to the squaring and lining mechanism.

Another object consists in providing such an apparatus which includesmechanism for temporarily limiting the movement of certain parts so asto facilitate repetition of the same operation without the necessity ofrepeated adjustment.

Another object consists in providing such an apparatus which includesimproved means for holding the work.

Another object consists in providing such an apparatus which containscertain improvements in the form, construction and arrangement of theseveral parts, whereby the above named and other objects may-be e'ffectively attained.

The translucent table and lighting means herein shown and described, butnot claimed, forms the subject matter of my co-pending aimlicationSerial No. 571,398. filed June 28th, 1922.

The apparatus includes a base 1 which is provided with suitable lugs 2for the reception of lag-screws or the like for securing the apparatusin position on a stand or other convenient support. A sturdy pillar 3 iscentrally fixed on the top of the base 1 by cap screws 4, and isencompassed by a hollow leg 5 to the upper end of which is fixed, bymeans of screws 6, a bracket 7 (see Fig. 5).

On the bracket 7 there is secured by screws 8 (see Fig. 1) an openrectangular framework 9. The framework 9 is rabbeted for the receptionofa ground glass top 10 which is firmly held therein by a filling ofcementitious material 11, such as plaster of Paris. The framework 9 andtop 10 constitute the table for supporting the work, which may be anegative or a plate, and it will be understood that the glass top 10 istranslucent.

Thetable 9. 10, is fitted with clamping mechanism for temporarilyholding the work in position thereon. This clamping mechanism (see Figs.4 and 5) consists of a pair of jaws 12, 13 which are rabbeted for thereception of the negative or plate that constitutes the work 14. Each ofsaid jaws has a set of yielding plugs, 15, composed of rubber or thelike, which are set into the rabbets and protrude slightly forengagement with the edge of the work. Thus the work may be firmly heldwithout any danger of injury.

The jaw 12 is pivoted to the ends of a pair of swinging arms 16, 17 eachof which has its other end fulcrumed by integral stems 18, 19, in bosseswhich project laterally from the table frame 9. The arm 16 is designedto operate idly on its fulcrum, while the arm 17 has a bell crank lever,including two branches 20; 21 fixed to the lower end of its stem orfulcrum 19. The branch 20 is connected by means of a retractile coilspring 22 with a pin 23 that is fixed in the frame 9, so that the innerend of the arm 17 is normally urged tothe right (see Fig. 4) so as toyieldingly force the jaw 12 inwardly toward the jaw 13. arm 17 imparts asimilar movement to the arm 16 through the intermediation of the j aw12. The jaw 13 is pivoted to the inner end of a swinging arm 24 theouter end of which is fulcrumed by anintegral stem 25 This movement ofthe in a boss formed on the side of the framework 9, while a bell crankhaving branches 26, 27 is fixed to the lower end of the'stem 25. Aretractile coil spring 28 is secured to the end of the branch 26 and toa pin 29 set in the frame 9. Thus it will be seen that the arm 24 ismount-ed and normally actuated in a manner similar to the arm 17, withthe result that the jaw 13 is normally urged toward the jaw 12 under theinfluence of the spring 28.

An eccentric 30, having an operating handle 31, is set in a bracket 32that is secured to one side of the framework 9, and a pair of rods 33.34 are pivoted at opposite sides of the eccentric 30, as indicated at 35and 36. Each of these rods has its free end bored and adapted for thereception of male screws 37, 38 that are arranged for rotatable butfixed against sliding movement in sleeves 39, 40 which. are pivoted tothe branches 21 and 27 of the bell cranks by screws 41, 42. The outerends of the screws 37, 38 are fitted with milled heads 43. 44 formanually adjusting the same; and it will be noted that, by turning thesaid heads. the effective length of the rods 33, 34 may be altered so asto fix the normal position of the jaws 12. 13. From the foregoingdescription it will be observed that, by swinging the lever 31, the jaws12 and 13 may be retracted from each other against the tension of thesprings 22 and 28; while, when the lever 31 is re leased, the saidsprings will urge the said jaws toward each other until they come intocontact with the work. A bolt 45 passes through the eccentric 30 andbracket 32, and has its upper end threaded for the reception of a tailnut 46 which may be actuated for clamping the eccentric 30 in anydesired adjustment.

A lever 47 (see Figs. 3, 5 and 11) has one end embracing with a bearingfit the reduced lower end of the hollow leg 5, and the said end of thelever 47 is enlarged and developed into a pair of outwardly anddownwardlv projecting feet 43 that are adapted to ride upon a curvedtrack 49 which is fashioned upon the top of the base 1. The upper partof the lever 47 carries an arcuate rail 50 and a wheel 51 is fixed inthe end of a laterall projecting stud 52 that is integral with thehollow leg 5, which said wheel is adapted to ride upon the rail 50 forsupporting the leg 5 and hence the table 9, 10. The disposition of thetrack 50 and wheel 51 such that, when the latter is on the former. theleg 5 will be supported slightly above the lower flange of the pillar 3so as to permit readyrotation of the leg on the pillar.

A pair of adjustable stops 53, are arranged on the inner end of thelever 47 adjacent each end of the arcuate rail 50: and the constructionis such. that when the wheel 51-rol-ls 01f either end of the said railit will drop slightly and bring the stud. 52 .into engagement with theadjacent stop 53. In such a position the wheel, and hence :the table 9,10, will be temporarily held against movement in either direction withrespect to the lever 47 until the wheel 51 is manually raised so as toagain rest upon the rail 50. The length of the rail 50 is such that whenthe stud 52 has passed from engagement with one stop 53 to an abutmentwith the other, the leg 5, and hence the table 9, 10, has traversed anarc of exactly 90;

About midway of its length the lever 47 rests upon a curved rack 54 (seeFigs. 5, and 11) which rack is toothed on its outer edge and graduatedinto degrees. The zero point is midway of the rack and the graduationsextend for a distance of about 70 on either side thereof. The rack issecured to the base 1 by means of screws 55, and it is calculated thatthe lever 47 shall slide upon the upper surface of the rack during. theswinging movement of the lever to be hereinafter described.

Mechanism is provided for causing the lever to have engagement with theteeth on the rack 54 and for adjusting the said lever in eitherdirection along the rack. This mechanism consists of a pinion 56 (seealso Figs. 12, and 13) that is rotatably mounted, by means of a screw 57in a rocking arm 58 which is pivoted by a screw 59 in the upper part ofthe lever 47. The rocking arm 58 has a grip 60 which is formedintegrally therewith and protrudes outwardly adjacent the outerextremity of the lever 47. A retractile coil spring 61 has one end fastto the extremity of the rocking arm 58, adjacent the pinion 56 and theother end anchored to a pin 62 fixed in the side of the lever 47. Theaction of the parts just described is such that the pinion 56 isnormally held in mesh with the teeth on the rack 54, while the operatormay, by seizing the grip 60 together with the end of the lever 47 swingthe arm 58 about its pivot 59 so as to withdraw the pinion from therack. In this withdrawn position it will be obvious that the lever 47may be manually swung to the right or left at will. This mechanism alsocomprises a device for rotating the pinion while in mesh with the rackso. as to finely adjust the lever 47 in either direction for the purposeof supplementing the less accurate movement of the lever when it ismanually swung, as just described. This device is a shaft 63, which isjournaled at 64a-nd 65 in the lever 47, andhas its inner end providedwith a worm 63* which engages the pinion 56. A milled head 66, which isfixed to the outer end of the shaft 63, serves for the manual operationthereof; and it will be understood that the turning of the shaft 63inithis manner will impart slow rotation to thepinion 56 and therebymove the lever 47 to the right or left as the case may be. A sight 67 isformed in the lever 47 so as to permit the reading of the graduations onthe rack therethrough.

F rom. the foregoing description it will be clear that, when the table9, 10 has been turned to either of its extreme positions with respect tothe lever 47 so that the wheel 52 is resting against one of the stops53, the movement of the lever 47 either by direct manual operation orthrough the actuation of the shaft 63, will swing the table 9, 10 to theright or left a corresponding distance. Furthermore, in whateverposition the lever 47 may be, the table may be shifted to right or lefta distance of 90 with respect to the lever, by the hand of the operator.

As before noted, the table top 10 is translucent and means is providedfor thoroughly illuminating the work (negative) 14. This means comprisesa. pair of electric lights 68 which are fast in reflectors 69 (see Figs.9 and 10) that are secured to brackets 70, which latter are fixed atopposite sides of the frame 9 by screws 71. These reflectors 69 may becomposed of suitable sheet metal such as polished aluminum, and it willbe noted that the reflectors pass around the out side of the lights andproject inwardly and downwardly beneath the lights so as to reflect thelight upwardly. In order to more brilliantly reflect the light and to beable to intensify the illumination of the work at any desired portionthereof, I have provided a pair of reflecting mirrors 72, which arehinged on a common pintle 73 which is mounted in lugs 74 depending fromthe frame .9, as clearly shown in Figs. 5 and 10. Theserefiectingmirrors 72 project downwardly and outwardly so as to be complementary tothe reflectors 69, and their angularity may be varied by adjusting rods75. Each of these rods in rotatably mounted in but fixed againstlongitudinal movement in sleeves 76 which are pivoted at 77 in the sidesof the frame 9. The extremities of the rods 75 are threaded into tappedsleeves'78, which are pivoted at 79 on the edges of the reflectingmirrors 72. Each mirror has one rod 75 connected to it and the said rodsare located at opposite sides of the frame 9. Milled heads 80 are pinnedto the upper ends of the rods 75 for manual operation thereof. It willbe clear that, by changing the angularity of the mirrors 72, the angleof reflection will be changed so as to vary the intensity ofillumination of different portions of thework. The wires (not shown) forthe lights 68 may be led from a suitable source of current supplythrough an opening in the base 1, a tube 81, composed of insulating material, located within the pillar 3, and thence through a pair of branchtubes 82. also composed of insulating material, and leader 82* to thelightsfiS. 1 I.

The squaring or lining mechanism will now be described. A pair of rulers83 (see Fig. 1) are slidably mounted, asat 84:, upon a cross bar 85which is journaled in bearings 86, 7 that are carried by stanchions 88,89 (see also Fig. 1) mounted on the base 1.

The cross bar 85 is threaded, as shown at.

90 for engagement with a pinion 91 (see Fig. 3) which is carried by aspindle 92 mounted in the upper part of the stanchion 89. A hand wheel93 is splined to the spindle 92 for manually operating the pinion 91;and it will be understood that the rotation of the said pinion willslide thebar 85 longitudinally in its bearings so as to move the rulersS3 in the same direction across the top of the table. The purpose ofthis provision is to enable the operator to bring the rulers into such aposition that they will embrace-the desired portion of the subjectmatter on the work. A thumb screw 94: is threaded onto the upper end ofthe spindle 92 and may be manipulated to act as a lock-nut to prevenaccidental movement of the bar 85.

liflechanisin is also provided for simultaneously moving the rulerstoward or away from each other; and this includes a pair of racks 95,one secured to each of the rulers 83. These racks mesh with a commongear 96 (see Figs. 7 and 8) that is keyed to a bolt 97 which is fittedin a bracket 98 secured to the bar 85 by means of set screws 99. A handwheel 100 is keyed to the upper end of the bolt 97, so that the bolt maybe rotated and hence actuate the gear 96 to move the racks 95 inopposite directions, in a well understood manner; this movementimparting corresponding movement to the rulers 83. The purpose of thisarrangement is to enable the rulers to be set so as to include betweenthem the desired amount of the work; or, in other words, to enable themarking of the work so that it may be out to the desired dimensions. Athumb screw 101, is threaded onto the upper end of the bolt 97forlocking the parts against movement.

This ruler actuating mechanism includes a micrometer gage which consistsof a plate 102 that issecured to the bracket 96 by pins 103. A disc 1041has its periphery beveled and fitted in an angular recess tashioned inthe top of the plate 102. as clearly shown in Fig. 7. The bevel of thedisc 104 may he graduated into inches and tr-actions thereof, or intopoints and picas; may be dc sired. In the present instance it is shownas divided into twelve inches. with subdivisioi'is, as illustrated inFig.6. The plate 102 has an upwardly extending sleeve 105 whichsurrounds the bolt 97. and the inner part of the disc 10% rests upon theflange of a sleeve 106 which surrounds the sleeve 105. The flange of thesleeve 106 extends between the plate 102 and the disc 10%. A pin 107serves to lock the hand wheel 100 to the sleeve 106. A washer 108 restsupon the the sleeve 106 together. Hence, the rotation of the hand wheel100 for the purpose of actuating the rulers 83, as just described,

will simultaneously rotate the disc 104 upon the plate 102, andthepassage of the graduations on the said disc by the Zero point, whichis marked on the plate 102 (see Fig. 6), will present to the eye of theoperator information asto the distance the rulers have been moved towardor away from each other. Consequently, the desired sep' aration of therulers may be readily predetermined and effected. Means is also providedfor temporarily limiting the rotary movement of the bolt 97, and hencethe movement of the rulers 83 in either direction, so as to enable thelatter to be repeatedly set at given points for determining the liningof, the work to establish its width and depth, without the necessity ofobserving and setting the micrometer disc. This means includes a pair ofwhat I call limit steps, which consist of two collars 110,

1.11 that embrace thesleeve 106 and lie adjacent each other. Thesecollars are split, as clearly shown in Fig. 6, and have enlargedportions contiguous the line of severance. One of the said enlargedportions on each of the collars is bored and interiorly threaded for thereception of threaded thumb, screws 112, 113 which have shoul-.

ders that bear against the outer part of the other enlarged portions. Itwill be understood that each of the collars 110 and 111- are the samewith respect to the construction just described. As will be clear, theoperation of the thumb screws will serve to tighten or loosen thecollars so that they will firmly grip or rotate with respect to thesleeve 106. Each of the said collars has a tail 114i, 115 which projectsradially and is adapted to contact with an upstanding post 116, which isset into the rear part of the plate 102. As a result of thisconstruction it will be seen that. when the thumb screws 112, 113 aretightened, the engage ment of the tails 1141. 1.15 with the post 116will terminate rotary'inovement ot' the bolt 97 and hence stop themovement of rulers 83. In operating this mechanism the hand wheel 100may be turned until the rulers 81-3 have been set to the desiredseparation for determining the width of the work. At this juncture oneof the collars 110. 111 is turned so as to bring its tail in contactwith the post 116 and its thumb screw, 112 or 113 as the case may be, istightened. The hand wheel. 100 is then turned in the opposite directionuntil the rulers have been set-the proper distance for lining the depthof the work, and the other of the collars 110, 11.1 is turned until its.tail contacts with the other side of the post 116. The thumb screw inthe last named collar is then tightened. l/Vith the parts in thiscondition it is simply necessary forthe operator to turn the wheel 100in one direction until tail of a collar abuts the post 116, at whichtime he will know that the rulers have been properly set for the widthof the work. In the next operation it is merely necessary to turn thewheel 100 in the reverse direction until the tail of the other collarabuts the post, at which time the rulers will be properly set for thedepth of the work. This contrivance thus enables rapidity in using theapparatus when it is desired to line or square a series of plates of thesame size. When the collars 110, 111 are not being used their tails maybe fixed against the post 116 by dropping the bent locking pin 117,which is carried by the tail 114, into the hole in the tail 115.

It has been mentioned above that the cross bar 85 may be slidlongitudinally for causing the rulers to encompass the desired portionor content of the work. In this connection I have also provided stopmech anism for enabling the rulers to be repeatedly set at any desiredpoint with respect to the work, without the necessity of examination. Itwill be understood that this refers to the simultaneous movement of therulers in the same direction over the work and has nothing to do withthe separation of the rulers from each other. This stop mechanismconsists of a pair of stops 118, 119 (see Figs. 1, and 4) that areslidably mounted on a rod 120 and have set screws '121, 122 fortemporarily fixing them in any desired position on said rod. The rod 120has one end fixed in a crank handle 123, which is fast to an end of thebar 85; and the rod 120 traverses a bearing 124 which is formed in theend of an arm 125 (see Fig. 2). The arm 125 has a sleeve 126 thatprojects laterally within the journal 86 and has a circumferentialgroove fitted to receive the point of a screw 127 that is threaded inthe top of the journal 86. The sleeve 126 has a free sliding androtating fit with respect to the bar 85. This construction prevents thearm 125 from moving when longitudinal motion is imparted to the bar 85.In using this mechanism the operator actuates the hand wheel 93, aspreviously described, until the bar 85, and hence the rulers 83, havebeen moved to the proper position for containing the desired content ofthe work when the latter is held in position to be lined for its width.The stop 118 is then slid along the rod 120 until it abuts the bearing124, in which position it is secured by the screw 121. The wheel 93 isthen turned in the reverse direction so as to slide the rulers 83 intothe proper position for bounding the desired content of the work when itis in position to be lined for depth. The other stop 119 is now slidalong the rod 120 until it abuts the bearing 124, in which position itis fixed by the screw 122. Now it will be seen that, for resetting therulers 83 with respect to the content of the work in subsequentoperations involving the same subject, it is merely necessary to turnthe wheel 93 until first one and then the other of the stops 118, 119contact with the bearing 124.

In order to enable the rulers to be swung out of the Way when desired,the bar 85 has a second crank handle 128 fixed to the other end thereof,by which it may be manually turned so as to elevate the rulers into avertical position. Suitable mechanism is provided for yieldinglyretaining the rulers in either of the said positions; which mechanismconsists of an angle arm having two parts, 129 and 130; the said armbeing pivoted at 131 in the stanchion 88. The part 130 of the angle armis connected by means of a retractile coil spring 132 with the j ournal86, so that the part 129 is normally urged forwardly. This part 129 hasa flatface which is calculated to contact with lugs 133, 134 and 135that are carried by the arm 125. It will be noted that the said lugsform, collectively, abutments disposed at right angles to each other.When the bar 85 is turned by the crank 128 so as to bring the rulersdown upon the Work, the lugs 133, 134 contact with the flat face of thepart 129, whereby the rulers are yieldingly held in the stated position.When the latter are elevated the arm 125 rides around on the lug 133until the lug 135 comes into contact with the flat face on the part 129;in which condition the rulers will be held in elevated position.

The apparatus also includes registering mechanism for insuring theproper positioning of the several plates of a series, such as a set ofcolor plates. This mechanism consists of a standard 136 that is set intoa hole formed in a plate 137 which is screwed to the base 1. Thestandard 136 is bifurcated at its upper part and the said bifurcationscarry trunnions 138, 139, the former of which is adjustable. Thesetrunnions are adapted to enter recesses in the ends of a shaft 140 forsupporting the registering arms. The said arms are denoted by 141 andare of identical construction. Each arm is adapted to be adjustably heldin a clamp which comprises two plates 142, 143. The plates 142 areformed integral with bearings 144, that are fixed on the shaft 140. Tailnuts 145 serve to draw the plates 142, 143 toward each other forsecuring the arms 141 in any desired adjustment therein. The arms 141have their free ends provided with articulated fingers which are ofidentical construction so that one only need be described. Each fingerhas a socket 146 that fits over the end of the arm 1 11 for securing thefinger thereon. This socket forms part of the first section 147 of thefinger; the other two sections being denoted by 148 and 149. I Eachsection has its abutting ends enlarged, as clearly shown in Fig. 17, inorder to provide broad bearing surfaces; and the parts are held togetherby bolts 150, 151 which have milled ends 152, 153 threaded thereon formanual operation. Leaf springs 154:, 155 are secured to the sections byscrews 156, 157 and bear against washers surrounding the bolts 150, 151below the nuts, in or der to provide a certain stifi'ness to the jointseven when the nuts are loosened. A registering pointer 158 is mounted inthe section149 of each finger. An expansion coil spring 159 surroundseach pointer within its section 149, for normally elevating the pointersso as to sheath their points within the said sections. A finger grip 160on each section 1&9 assists the operator in grasping the fingers anddepressing the pointers with his thumbs. In using this adjustingmechanism, the operator loosens the tail nuts 145 and the thumb nuts152, 153. He then brings the pointers 158 in coincidence with selectedspots on the work or with registering points marked thereon. The nuts14:5, 152 and 153 are then tightened. After this operation the arms 1&1may be swung outwardly during which movement the shaft 1441 turns on itstrunnions 138, 139. When a second plate of a series is placed inposition, the arms 1&1 are again lowered, and the plate moved until thepreviously selected points or particular in dicating points are inregister with the points 158. This will insure the exact registering ofthe second plate with the first;

. and the same procedure may be followed with subsequent plates of thesame series. In order to hold the arms l i-1 in their inoperative,elevated position, I provide a spring clamp which includes a member 161that is pivoted to the standard 136 at 162 and normally urged inwardlyby a. retractile coil spring 163 which is connected to the member 161and anchored to a bracket 16 1 carried by the standard 136. A rightangle member having two faces 165, 166 is mounted freely on the shaft1&0, and is adapted to be secured to a complementary member 167 that isfixed to the shaft 140. The means for securing these two memberstogether consists of a pin 168 that is threaded into a projection on theright angle member 165, 166, and traverses a slot 169 formed in the endof the member 167, and has a tail nut 170 thereon. The slot 169 permitsof the said members being adjusted relatively to each other forproviding a slight field of adjustment of the pointers 158 toward andaway from the work. When the arms 141 are in the lowered position thepart 161 engages the face 166 of the right angle member with a yieldingpressure for retaining the arms 141 in said position. When the said armsare elevated the part 161 has a similar engagement with the face 165 fora similar purpose.

In order that the registering mechanism may be thrown completely out ofthe way I provide the standard 136 with a stud 171 carrying a wheel 172that rides upon a track 173 formed on the plate 137. Abutments 17 4 areformed on the said plate for contact with the stud 171 when the wheelhas passed off either end of the track. It will be seen that thisarrangement is similar to that of the wheel 51 and its associated partsand that the construction is such that the registering mechanism may beturned through a quarter circle either toward or away from the worktable.

In order to accommodate plates of irregular form and to provideconvenient means for adjusting them with respect to the registeringmechanism, I have devised a holder 175 (see Fig. 1 1) which consists ofa frame that is adapted to be seized by the jaws 12 and 13, and held inposition on table. The said frame carries three adjusting screws 176,that have heads fitted to slide in grooves formed in the frame. Thescrews 176 are threaded into the edge of the frame and provided withknurled heads for manual adjustment. It will be seen that, by thisarrangement, a small plate, such as that indicated by 177, may bereadily moved so as to bring its adjusting points into precisecoincidence with the points 158.

A suitable work holding rack 178 may be bolted on the base 1, as shownin Fig. 1, and the stanchion 88 may have a socket 179 and set screw 180for receiving the end of a rod (not shown) designed to support a lightfor providing suitable illumination above the work.

I believe that the operation of the apparatus will be clear to anyoneskilled in the art from the foregoing description, when takenin-connection with the drawings, but the same may be briefly stated asfollows:

The work 14 is clamped in the jaws 12, 13 in the manner described. Therulers 83 are lowered to rest upon the work, and the table is turned byoperating the head 66 on the shaft 63 until a selected vertical line orsquaring line is parallel with the rulers. The rulers are set, by meansof the wheel 100, to the distance apart selected fonthe width of thework. -The rulers are then moved by the crank 128 and bar 85 until theyembrace the desired content of the work. Vith a sharp edged tool thework is marked with lines for the cutter to follow in a sub sequentoperation. It will be understood that during the procedure justoutlined, the table has been in such position that the the desirednumber of degrees.

wheel 51 is resting against one'of'thestops 53. The operator now movesthe table so that the said wheel rests against the other stop 53, whichmovementwill swing the table through a quarter circle and bring the twoother sides of the work under the rulers in order that it may be markedfor depth. In this position of the table the procedure above describedis repeated. v

In the case of color printing it is frequently desirable to photographplates at different angles on the copy board so as to obtain desirablescreen effects. For instance, one plate may be set at from its normalperpendicular, another 60, etc. However, the said plates must be allsquared orlined for squaring so that they will print in the sameposition. The parts above-described embody means for readilyaccomplishing this result in that the table may be swung to the right orleft of its normal position For in stance, the first plate of a colorseries may be placed in position in the jaws 12, 13 and squared andlined as already described. When the second plate of the series (whichhas been photographed at a 30 angle) is placed in the jaws, it is merelynecessary to swing the table a distance of 30 in the proper direction,to bring this plate intthe.

desired alinement with the rules. This relatively large swingingmovement of the table may be accomplished by seizing the end of thelever 47 and pressing the grip so as to release the pinion 56 fromcontact with the rack 54, and manually moving the said lever to theright or left as the .case may be. Vhen in approximately the desiredposition the pinion 56'may again be permitted to mesh with the rack, andthe table may be swung to the exact position by turning the head 66 ofthe shaft 63. In this position the second plate may be lined; and itwill be-borne. in mind that this swinging of the table to any extentwhatever does'not affect the relationship ofthe table and the lever 47.Hence in whatever position theparts may be, the table is always adaptedto be swung through an arc of precisely 90' with respect to the lever 47so as to present the work in the different positions for lining it as towidth and depth. It will be clear that subsequent plates of thecolor-series, which have been photographed at-yarious other angles, maybe handled in a precisely similar manner. I At any desired-time theregistering mechanism may be brought into play and used as described. i

It will be understood that various changes may be resorted to in theform, construction, and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence I do notintend togbe limited to "the details here- .in shown anddescribed'except as they may be specifically included in the claims.'What I claim is: I
